15 صفحه اولRestriction endonucleases and modification methylases in bacteria.
There are three mechanisms by which foreign DNA may enter a prokaryotic organism: conjugation between Gram-negative bacteria, uptake of exogenous DNA (transformation) and infection by viral (bacteriophage) nucleic acid. The interaction between a bacteriophage and its host bacterial cell has been extensively investigated. A bacterium can restrict phage infection through its ability to degrade th...
متن کاملEcoR124I: from plasmid-encoded restriction-modification system to nanodevice.
SUMMARY Plasmid R124 was first described in 1972 as being a new member of incompatibility group IncFIV, yet early physical investigations of plasmid DNA showed that this type of classification was more complex than first imagined. Throughout the history of the study of this plasmid, there have been many unexpected observations. Therefore, in this review, we describe the history of our understan...
متن کاملDNA restriction-modification systems mediate plasmid maintenance.
Two plasmid-carried restriction-modification (R-M) systems, EcoRI (from pMB1 of Escherichia coli) and Bsp6I (from pXH13 of Bacillus sp. strain RFL6), enhance plasmid segregational stability in E. coli and Bacillus subtilis, respectively. Inactivation of the endonuclease or the presence of the methylase in trans abolish the stabilizing activity of the R-M systems. We propose that R-M systems med...
